Description

Technical Field

[0001] The utility model relates to the technical field of relay compression springs, in particular to a compression spring structure which is easy to assemble and has an anti-dropping and adjustable function. Background Art

[0002] Relay is an electronic control device that plays the role of automatic adjustment, safety protection, circuit conversion, etc. in the circuit. It is widely used in power protection, automation, motion, remote control, measurement and communication devices. The compression spring is a relatively important component of the relay. It is often used with the moving parts to press the moving parts to achieve functions such as anti-vibration, buffering and noise reduction, and limit. Therefore, the consistency and stability of the compression spring installation are very important to the relay.

[0003] If the existing relay compression spring falls off or the compression spring structure is deformed during use, the moving parts will not be able to support the relay, the seismic resistance of the relay will be reduced, the noise will increase when the relay is operated, and even the moving parts will fall off, causing the relay to malfunction; if the pressure of the compression spring is too large, it will affect the normal operation of the relay moving parts, and the relay may not operate or malfunction. Therefore, a compression spring structure with a stable structure, not easy to fall off, controllable and adjustable pressure, and easy to install is needed. Utility Model Content

[0010] As mentioned above, the pressure regulating component is a tongue spring, and the tongue spring is integrally formed with the flat plate and is located on the inner wall of the opening of the compression spring flat plate.

[0011] Beneficial effects:

[0012] Compared with the prior art, the compression spring structure with simple assembly and adjustable anti-dropping function has the following beneficial effects:

[0013] 1. The utility model provides a compression spring plate and a tongue spring, so that the entire compression spring plate is inserted into the relay so that it abuts against the root of the movable part of the relay, so that the root of the movable part cannot be displaced, and the top of the movable part can move, so that the root of the movable part is equivalent to a fulcrum, and the top of the movable part is deflected at an angle. At this time, the tongue spring can also abut against the root of the movable part. When the tongue spring is subjected to excessive pressure, the bending angle of the vertical side of the compression spring plate will also change, which will play a buffering role. This double buffering design structure makes it difficult for the compression spring plate and the tongue spring to be permanently deformed. At the same time, the bending angle of the tongue spring can be adjusted, so that the pressure of the compression spring plate can be adjusted.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-4As shown, the utility model provides a technical solution: a simple assembly with anti-drop adjustable compression spring structure, comprising a compression spring plate 1, the front of the compression spring plate 1 is penetrated by an opening 4, and the inner wall of the opening 4 is provided with a pressure regulating component;

[0023] The compression spring plate 1 is a plate of elastic material, which is formed by bending and is L-shaped. Anti-slip components are arranged on both sides of the lower end of the compression spring plate 1.

[0024] According to the overall structure of the device, the compression spring plate 1 is inserted into the plastic base of the relay, and after installation, it is interference fit with the plastic base. The anti-slip convex rib 3 in the convex rib groove 5 is equivalent to a barb, forming an anti-slip structure, so that the compression spring plate 1 is against the root of the movable part of the relay, so that the root of the movable part cannot be displaced, and the top of the movable part can move, so that the root of the movable part is equivalent to a fulcrum, and the top of the movable part is deflected at an angle. At this time, the tongue spring 2 can also be against the root of the movable part. When the tongue spring 2 is subjected to excessive pressure, the bending angle of the vertical side of the compression spring plate 1 will also change, which will play a buffering role. This double buffering design structure makes it difficult for the compression spring plate 1 and the tongue spring 2 to be permanently deformed. At the same time, by adjusting the bending angle of the tongue spring 2, the pressure of the compression spring plate 1 can be adjusted.

[0025] like Figure 2 As shown, the anti-slip component is an anti-slip rib 3, and both side surfaces of the lower end of the compression spring plate 1 are torn and bent to form an anti-slip rib 3.

[0026] By setting the anti-dropout rib 3, the compression spring plate 1 can be inserted into the plastic base of the relay. After installation, it will be interference fit with the plastic base. The anti-dropout rib 3 is equivalent to a barb, forming an anti-dropout structure, so that the compression spring plate 1 is not easy to fall off. When the compression spring plate presses the armature, the root of the armature is immobile and the top can move.

[0027] like Figure 3 As shown, the pressure regulating component is a tongue spring 2, which is integrally formed with the plate and is located on the inner wall of the opening 4 of the compression spring plate 1.

[0028] By setting the tongue reed 2, when the tongue reed 2 is subjected to excessive pressure, the bending angle of the vertical side of the compression spring plate 1 will also change, which will play a buffering role. This double buffering design structure makes it difficult for the compression spring plate 1 and the tongue reed 2 to undergo permanent deformation. At the same time, by changing the bending angle of the tongue reed 2, the pressure of the compression spring plate 1 can be adjusted.

[0029] Working principle: insert the compression spring plate 1 into the plastic base of the relay, and after installation, it will have an interference fit with the plastic base. The anti-slip convex rib 3 in the convex rib groove 5 is equivalent to a barb, forming an anti-slip structure, so that the compression spring plate 1 can be pressed against the root of the movable part of the relay, so that the root of the movable part cannot be displaced, and the top of the movable part can be moved, so that the root of the movable part is equivalent to a fulcrum, and the top of the movable part is deflected at an angle. At this time, the tongue spring 2 can also be pressed against the root of the movable part. When the tongue spring 2 is subjected to excessive pressure, the bending angle of the vertical side of the compression spring plate 1 will also change, which will play a buffering role. This double buffering design structure makes it difficult for the compression spring plate 1 and the tongue spring 2 to be permanently deformed. At the same time, by adjusting the bending angle of the tongue spring 2, the pressure of the compression spring plate 1 can be adjusted.
